Radio receiver and method for receiving and playing signals from multiple broadcast channels

ABSTRACT

A radio receiver may comprise a receiver adaptable for receiving a plurality of broadcast streams over a plurality of broadcast channels, wherein the receiver will attempt to receive a selected broadcast stream on a selected broadcast channel, and if the selected broadcast stream is not receivable on the selected broadcast channel, the receiver will attempt to receive the selected broadcast stream on an alternative broadcast channel. A computer readable medium may allow a user of a receiver to create a composite stream comprising at least one portion selected from each of at least two of a plurality of broadcast streams. A method of open interface merge replication may involve comparing data between first and second databases, and if a conflict exists, updating one of the first and second databases with at least a portion of data from the other of the first and second databases to resolve the conflict.

U.S. patent application Ser. No. 11/499,434 filed Aug. 4, 2006, Ser. No. 11/477,156 filed Jun. 27, 2006, and Ser. No. 11/365,545 filed Mar. 1, 2006 are incorporated herein by reference. The methods discussed in those references may be used as a basis for tagging or marking broadcast files used in some embodiments. One embodiment comprises a method of allowing a user to purchase or copy a broadcast file after tagging or marking the broadcast file on a receiver. A user may be given an opportunity to purchase the broadcast file electronically. The tags or marks may indicate where the broadcast file will be purchased from or copied from, for instance, from an iTunes® web site or other web site. The tags or marks may also indicate to other users of other receivers where they may obtain a license for the broadcast file. The tags or marks may indicate the artist, title of the song, or other data associated with the broadcast file.

One embodiment as described herein is directed to a portable or desktop radio receiver adaptable for receiving one or more broadcast streams on one or more broadcast channels. Some embodiments may allow a user of a portable or desktop radio receiver to create a composite stream from a portion of one or more broadcast streams.

Referring to FIGS. 1 and 2, a receiver 100 may comprise a computer and a memory and may be in communication with one or more sources of communications signals, such as FM, AM, HD, ST, and IP broadcast sources, for example, and one or more central computer systems 110. Each central computer system 110 may include but is not limited to a computer 104 and a data storage device 106 in communication with computer 104. Although only one computer 104 and data storage device 106 are shown in FIG. 2, more than one computer 104 and data storage device 106 may be provided. As shown in FIG. 2, a receiver 100 (indicated as R.sub.1 . . . R.sub.N) may be in communication with computer 104, either directly or via a network 102, which may include but is not limited to the Internet. Each receiver 100 may be capable of receiving communications signals over one or more broadcast channels from the various broadcast sources, such as the FM, AM, HD, ST, and IP broadcast sources shown in FIG. 1, as well as one or more composite streams (CS) from one or more central computer systems 110 as described further below. Each receiver 100 may also have a transmitter adaptable for transmitting communications signals to computer 104 of one or more central computer systems 110 as described further below. The communications signals transmitted between and among the broadcast sources, receivers 100, and one or more central computer systems 110 may include primary data, such as songs, advertisements, talk shows, game shows, DJ chatter, news reports, weather reports, traffic reports, and sports reports, for example, as well as ancillary data, such as EPG data 101, for example.

In some embodiments, EPG data 101 may contain metadata information within broadcast streams, such as radio, television, satellite, and Internet broadcast streams. EPG data 101 may include but is not limited to metadata information such as station names, station call signs, broadcast frequencies, broadcast channel types, broadcast stream types, program titles, album titles, song titles, artist names, genres, durations, start times, end times, affiliated station carriers, keyword(s), and other metadata information relating to one or more broadcast streams. One or more central computer systems 110 may include various computer program applications, such as an EPG update interface 111 and a device services interface 113 to facilitate open interface merge replication as described further below. Data storage device 106 of one or more central computer systems 110 may be used to store various data, such as EPG data 101 and user preference data.

In some embodiments, a receiver 100 may have the capacity to receive and display EPG data 101 and to tune, browse, capture or download a selected broadcast stream on an available broadcast channel using metadata information from an EPG. For example, receiver 100 may be programmed to browse EPG data 101 such as station call signs, and a user may select a certain station call sign such as “KISS FM,” for example. The receiver 100 may then be tuned to the user selected station, having the call sign “KISS FM.”

The receiver 100 may include volatile memory storage to be used as a buffer for real time listening, providing the receiver 100 the ability to rewind, pause, and fast forward up to a desired point. The receiver 100 may also incorporate an EPG to enable a scheduled recording of one or more selected broadcast streams or enable an immediate recording of real time programming. In some embodiments, a receiver 100 may have the capacity to receive and display EPG data 101 and to tune, browse, capture or download a selected broadcast stream on an available broadcast channel. A broadcast stream may be selected manually or according to predefined rules. For example, receiver 100 may be programmed to attempt to tune in to a selected broadcast stream over a selected broadcast channel, and if the selected broadcast stream is not available on the selected broadcast channel, receiver 100 may then attempt to tune in to the selected broadcast stream over an alternative broadcast channel. Receiver 100 may be programmed to continue to search for the selected broadcast stream on successive alternative broadcast channels according to one or more rules of priority, which may be predetermined or established by a user, until the selected broadcast stream is found or all available broadcast channels are exhausted. For example, a user may select a certain radio station, such as KISS FM, and receiver 100 may be programmed first to seek the KISS FM station on an HD FM broadcast channel, and if that fails then seek that station on a regular FM broadcast channel, and if that fails then seek that station on an IP broadcast channel. Of course, any desired rules of priority may be used, and the foregoing example is merely illustrative. Receiver 100 may be programmed such that if the selected broadcast stream is not available on any of the available broadcast channels, then receiver 100 may display a message or produce a signal indicating that the selected broadcast stream is not currently available, tune in to a default or alternate broadcast stream, or go into a sleep mode. The default or alternate broadcast stream may be determined according to user preference data, such as a preferred genre, for example. Receiver 100 may also be programmed such that if the selected broadcast stream is not available on any of the available broadcast channels, then receiver 100 may allow the user to select comparable broadcast streams.

Some embodiments may include a database that may store the availability of various broadcast streams on various broadcast channels. The database may be stored locally in a memory in receiver 100, remotely in data storage device 106, or in both of those locations. In various embodiments, the database may contain data for all available broadcast streams in a given geographic area. Using a receiver 100, a user may browse or tune to all broadcast streams accessible in a user selected geographic area. For instance, a user may program a receiver 100 to search for broadcast streams in a certain zip code. The receiver 100 may access the database stored locally in a memory in receiver 100, remotely in data storage device 106, or in both of those locations to determine all broadcast streams on various broadcast channels available in the selected zip code. Additionally, broadcast streams and broadcast channels may be searchable using the database based on a selected city, state, or distance from receiver 100. Other embodiments may allow a user to search for all broadcast streams and broadcast channels using the database based on the IP address of receiver 100, the GPS location of receiver 100, positional information of receiver 100, or other geographic location of the receiver 100.

Some embodiments allow a receiver 100 to upload data of various broadcast streams on various broadcast channels in a given geographic area to the database in order to effectively populate the database for the benefit of all users. For instance, if a user in San Antonio, Tex. tunes his or her receiver 100 to a selected broadcast stream over broadcast channels HD or FM, such user may upload the data from his or her receiver 100 to the database to benefit all other users in San Antonio, Tex. seeking to tune to the selected broadcast stream. If a second user using another receiver 100 travels to San Antonio, Tex., the second user's receiver 100 may download data from the database to locate the same selected broadcast stream over broadcast channels HD or FM. Of course, the same upload and download processes may be applied to any available broadcast channel, not merely HD or FM. The upload and download processes may be automatic or upon request. Uploading of data to the database may enable multiple users to share data about broadcast streams, broadcast channels, and user preferences among a plurality of receivers 100. For example, a local user in Rome, Italy may upload data to the database from that user's receiver 100 allowing a tourist user traveling in Rome, Italy, for instance, to download data from the database. The tourist may then tune to all available broadcast streams over various broadcast channels in Rome. As another example, a user in New York City may discover a new broadcast stream not previously stored in the database. The user may upload the newly discovered broadcast stream data to the database and allow other New York City users to tune to the newly discovered broadcast stream after downloading the data from the database.

Other embodiments may allow a user of a receiver 100 to automatically download data from the database at periodic intervals. A user may also manually download data to receiver 100 from the database. Receiver 100 may take various forms, such as a desktop device or a mobile handheld device. Some embodiments may include user preferences that may be stored in the database such that a user preference stored for a desktop receiver may be transferred to a mobile handheld receiver, or vice versa.

Each broadcast channel may have a theoretically unlimited number of broadcast streams using that broadcast channel as a transport mechanism. Broadcast streams may interact with a system as described herein in at least three ways:

1. EPG Data Upload—EPG data from each broadcast stream may be uploaded to central computer system 110 via an EPG update interface on a regular or otherwise determined basis. The composite of this information from all broadcast streams across all broadcast channels may form a master EPG, which may be stored on data storage device 106.

2. Content Broadcast—The content of a broadcast stream may be broadcast by a source and picked up by a receiver 100 using, for example, its multi-channel receiver functionality.

3. Backchannel Reporting—A receiver 100 may report backchannel data to one or more central computer systems 110 concerning one or more broadcast streams received by receiver 100. This backchannel data may include, but is not limited to, listener play information, such as information about the particular content played, the types of content played, when the content is played, where the content is played, and so forth. Such backchannel data may be used by broadcasters to provide particular information targeted to certain listeners or geographic areas in future broadcasts.

Persons of ordinary skill in the art will recognize that various data may be stored in various locations and in various formats in a system as described herein. For example, desired playlist data may be stored in memory on one or more receivers 100 and on data storage device 106, and the formats in those locations may not be the same. To facilitate the use of such data in an orderly manner, a method of open interface merge replication (“OIMR”) may be used. In such a system, certain data elements may at times be updateable in a variety of locations, such as, for example, on one receiver 100, another receiver 100 used by the same user, or data storage device 106, and those devices may not use the same data format. Also, of those devices, the situation may be such that no one data store is necessarily the “master,” that is, the device whose information prevails if a conflict exists.

FIG. 3 illustrates one embodiment of a method of OIMR. This method may allow two or more devices or databases 118 and 116, such as a memory of receiver 100 and data storage device 106 of one or more central computer systems 110, respectively, to be synchronized with each other as “requester” 114 and “synchronizer” 112. These devices may be able to store data locally, access data stored elsewhere, or both. Further, the data may or may not be of the same format. Such a solution may typically be oriented toward the synchronizer 112 being the master, but that need not be the case. The conflict resolution mode may be set as desired such that either the requester 114 or the synchronizer 112 wins any conflicts or “deltas” that are identified. The processing logic may be divided between the requester 114 and the synchronizer 112 in any relative amounts as desired. For example, a majority of the processing logic may be performed on whichever device is selected as the master. Depending on the particular situation, not all of the steps listed in FIG. 3 may be necessary, or additional steps may be included if desired.

Still referring to FIG. 3, a method of OIMR may involve a plurality of steps indicated as 1-15. For example, a requester 114 may request an update from a synchronizer 112, such as by sending a ping to a server. Such a request may be made, for example, manually, electronically, automatically or otherwise from time to time. In return, the synchronizer 112 may compare the data on the two devices and determine the differences, if any. Whether or not any differences or “conflicts” exist, the synchronizer 112 may then communicate an update of data to the requester 114, which may be accepted or rejected, for example, in accordance with predetermined instructions. On the other hand, the requester 114 may at times act as the master, such that any conflicts may be resolved in its favor. The data involved herein may include, for example, time settings, play lists, EPG information, records, recordsets or other data or portions thereof. The data, transactions, and/or devices involved in OIMR may be uniquely identified, such as by assigning a globally unique identifier (“GUID”) to each of them, in order to sufficiently distinguish the different pieces of data.

Referring again to FIG. 3, a method of OIMR may have a plurality of applications. For example, a receiver 100 may allow a user to arrange a “preset” such that the user may quickly recall a favorite broadcast stream with the push of a button. However, the user may have a second receiver 100 at home or another location with a different preset or may choose a different preset through a web interface provided by one or more central computer systems 110 shown in FIG. 1. In such a situation, for example, the user may wish that any changes to a preset made via the web interface automatically take effect on the home receiver(s) as well. Thus, questions may arise, for example, as to which user settings control, or whether the home receivers are affected by changes made elsewhere. A preset may be bi-directional. For example, a preset may be set on a local receiver and pushed up to a centralized server, or such preset may be set on a centralized server via a web site and pushed to a local receiver or other devices. A local database on a receiver may be incrementally updated such that a given update may not necessarily replace all of the database but may only update the difference in versions as needed or desired between the local database and a centralized database, for example. Each radio station, such as over the air (OTA), Internet, and HD2, for example, may be given a unique ID—for example, a KOGA-FM OTA station may have a different station ID than a KOGA streaming Internet station, and a KOGA HD2 station may have a different station ID than the OTA station and the streaming Internet station. While a preset is used herein as an example, other types of data, content or instructions may also be changed on various system components and in a variety of ways. Thus, changes or updates may be made to similar data in a plurality of locations.

Receiver 100 may be programmable to perform time shifted playback, in which a user may save some data to a local storage device on receiver 100 and play that content at a later time. Receiver 100 may also be programmable to allow a user to create personal playlists and send such playlists to another user, such as through the database discussed herein. Receiver 100 may also be programmable to allow a user to create a composite stream and distribute that composite stream, or an EPG for that composite stream, to others.

FIG. 4 illustrates the creation of an EPG-based composite stream 130 that comprises one or more pieces of data selected from one or more broadcast streams 120, 122, 124, 126, and 128. This functionality of receiver 100 may allow a user to create a unique “station” and to share it with others without having to have access to the physical equipment of the source of a broadcast channel or broadcast stream. For example, a user may compile a unique play list including his or her favorite streams or songs and may share that play list with others. Further, a user may, for example, record a series of selected songs from a variety of broadcast streams and may then have the ability to share that recording with other users. Composite streams may provide an avenue for the publication of a wide variety of specialized and unique broadcast streams without the need for additional broadcast channel infrastructure. This may create an environment for low cost experimentation with new data formats and also economic viability for niche content, or data, formats.

Receiver 100 may take various forms, such as a desktop device or a mobile handheld device that may dock in a car, at home, or runs off of a battery. One embodiment 115 of a receiver 100 is illustrated in FIGS. 5-7. Receiver 115 may have one or more N/W/T/S presets 11 for news, weather, traffic and sports. A user may create a playlist of one or more N/W/T/S presets 11, for instance, a sports playlist for sports broadcast streams in Dallas, Tex. In some embodiments, one or more N/W/T/S presets 11 may include broadcast streams targeted to school closings, or lunch menus at schools in a geographic area, for example. In other embodiments, one or more N/W/T/S presets 11 may include traffic data from various traffic services. A user may program which traffic routes and other data they are most interested in and the receiver 115 may display the data or traffic routes in either a text or graphical manner. Targeted news, weather, traffic and sports may therefore be broadcast to a receiver 115 based on a user's configuration.

Still referring to FIGS. 5-7, a receiver 115 may also include one or more channel presets 13; a tuning knob 19 for controlling tuning of receiver 115 while playing over the air (OTA) signals or WiFi signals; a volume and on/off knob 21; an infrared (IR) window 7 for communicating wirelessly with other communications devices; a record button 9 for recording data on receiver 115; a mute switch 15 for muting receiver 115; a display 17 for displaying information; an internal speaker 51 for playing sound; an alarm button 5 for activating or disabling a user configured alarm; and an included antenna 3 for receiving broadcast streams. Included antenna 3 may be a telescoping or other suitable type of antenna. Alternatively or additionally, an internal antenna may be provided. A snooze button (not shown) may also be included on the receiver 115.

Most radio alarms may only be configured to assign a buzzer or an FM or AM broadcast channel as the alarm sound. If the FM or AM broadcast channel is weak, the alarm sound may be radio static instead of the selected broadcast stream. In one embodiment, a receiver 100 may be programmed to assign a recorded playlist as the alarm sound. The receiver 100 may also be programmed to assign a user selected broadcast stream whereby if an FM or AM broadcast channel is weak, the receiver 100 may search for an alternative broadcast channel such as an HD or IP broadcast channel, for example. The receiver 100 may also be programmed to assign a default buzzer as the alarm sound. In some embodiments, the receiver 100 may be programmed to assign a podcast as the alarm sound. Other receivers 100 may include an alarm that can be programmed for dayparting, wherein at least two alarm settings, for instance from Monday to Friday, and Saturday to Sunday, are set.

Referring again to FIGS. 6 and 7, receiver 115 may include an FM antenna switch 25 to allow a user to select between the included antenna 3 or an external antenna (not shown); an AM antenna switch 26 to allow a user to select between the included antenna 3 or an external antenna (not shown); a 300.OMEGA. FM antenna connection 27; an AM antenna connection 28; a 75.OMEGA. FM antenna connection 29; a power connector 31; a network port 33; a wireless network port 35; a USB connector 37 for providing power and/or data to the receiver 115; line in/line out jacks 39 to allow the receiver 115 to connect to other audio/video sources or external speakers or other output devices; a headphone jack 41; an iPod adapter 42 to allow the receiver 115 to broadcast a communications signal from an external iPod; and a base 44. Network port 33, USB connector 37, and wireless network port 35 may be provided to allow the receiver 115 to connect to the Internet or other suitable network. Additionally, a receiver 115 may contain an internal wireless adapter to connect to the Internet or other suitable network. USB connector 37 may also be used to connect the receiver 115 to a computer to output sound or data from the receiver 115 to a computer's speakers or other suitable device. USB connector 37 may also be used to connect a computer to the receiver 115 to output sound from the computer to the internal speaker 51 of the receiver 115.

Referring again to FIG. 5, in some embodiments, a channel selector switch 142 may be included in the receiver 115 for manually selecting one or more broadcast channels, such as AM, FM, HD, or WiFi, for example. Other embodiments may seamlessly switch between available broadcast channels without any manual selection. For instance, HD digital and IP broadcast channels normally have a time delay in broadcasting the communications signal. A receiver 115 may first select broadcast channels FM or AM after a user selects a broadcast stream, then automatically switch to an HD digital broadcast channel to avoid any time delay. Alternatively, a user may manually force a receiver 115 to a certain broadcast channel using channel selector switch 142. For instance, a user may be located in a building with poor FM or AM reception. Therefore, a user may program the receiver 115 to only tune to broadcast channels such as WiFi or other Internet broadcast channels, for example.

Some broadcast channels or broadcast streams require a subscription or payment of some form to receive and use the broadcast stream or broadcast channel. For instance, some satellite radio stations require subscriptions to receive their broadcast stream. Many conditional access broadcast streams or broadcast channels use NDS technology to encrypt the signal, and typically require some form of a pass card or ID to enable the broadcast stream or broadcast channel. Of course, other forms of identification may be used to enable the broadcast stream or broadcast channel. In one embodiment, a receiver 100 may access conditional access broadcast streams or broadcast channels by using a pass card or ID. The receiver 100 may also support downloading podcasts directly to the receiver 100 based on standard RSS subscription processes or other suitable methods. In an alternative embodiment, a receiver 100 may allow a broadcast stream to be marked or tagged by the user as a purchase interest.

What is claimed is:
 1. A method of merge replication, comprising: accessing a first database and a second database, each of the first database and the second database including information related to one or more media broadcasts, wherein one of the first database and the second database resides on a first radio receiver and the other of the first database and the second database resides on a second radio receiver; comparing data between the first database and the second database, wherein one of the first and second databases includes information indicating a first preset broadcast stream, and the second radio receiver includes information indicating a second preset broadcast stream; in response to an interaction between a user and a web interface to change one the first preset broadcast stream and the second preset broadcast stream, determining whether a conflict exists between the first database and the second database, wherein the conflict includes a difference between the first preset broadcast stream and the second preset broadcast stream; if a conflict exists: determining whether the first database or the second database should control the resolution of the conflict; and updating one of the first database and the second database with at least a portion of data from the other of the first database and the second database to the extent necessary to resolve the conflict by applying any changes made to one of the first preset broadcast stream and the second broadcast stream to the other of the first preset broadcast stream and the second broadcast stream.
 2. The method of claim 1, wherein the first database has a first format and the second database has a second format different from the first format.
 3. The method of claim 2 wherein one of the first database and the second database resides on a radio receiver and the other of the first database and the second database resides on a central data storage device.
 4. The method of claim 1, comprising: determining that the first database should control the resolution of the conflict; and if a conflict exists, updating the second database with at least a portion of data from the first database to the extent necessary to resolve the conflict.
 5. The method of claim 1 wherein data associated with at least one of the first database and the second database are each uniquely identified by a globally unique identifier.
 6. A radio receiver comprising: a first computer readable medium comprising a local database adaptable for storing data representative of one or more broadcast streams that are receivable over one or more broadcast channels, wherein the data includes information indicating a first preset broadcast stream; a second computer readable medium comprising a computer program; a computer in communication with the first computer readable medium and the second computer readable medium; and the computer program comprising instructions to cause the receiver to transmit, in response to a user using the radio receiver to change information related to the first preset broadcast stream, at least a portion of the data indicating a first preset broadcast stream to a second database remote from the receiver.
 7. The radio receiver of claim 6, the computer program comprising instructions to cause the receiver to transmit at least a portion of the data to the second database remote from the receiver in response to identifying a conflict between the local database and the second database.
 8. The radio receiver of claim 7, the computer program comprising instructions to cause the receiver to transmit at least a portion of the data to the second database remote from the receiver to resolve the conflict.
 9. The radio receiver of claim 6, the computer program comprising instructions to cause the receiver to transmit at least a portion of the data to a central database remote from the receiver to be pushed to one or more other databases of one or more other remote radio receivers.
 10. The radio receiver of claim 9, the computer program further comprising instructions to update the local database, in response to receiving data from the central database, to at least partially reconcile a difference between the local database and the central database.
 11. The radio receiver of claim 9, the computer program further comprising instructions to update the local database in an incremental manner, in response to receiving data from the central database, to at least partially reconcile a difference between the local database and the central database.
 12. The radio receiver of claim 6, comprising: the local database adaptable for storing data representative of one or more composite broadcast streams that are receivable over one or more broadcast channels, the one or more composite broadcast streams individually comprising at least one portion selected from each of at least two of a plurality of broadcast streams; and the computer program comprising instructions to cause the receiver to transmit at least a portion of the data representative of one or more composite broadcast streams to a second database remote from the receiver.
